Little more flex
I got the 3/4 " x 3 ' Proflex cleaning rod to add a little more flex to the brush end of my 7/8 ' x 5 ' Proflex cleaning rod system. I have two 30 degree offsets to snake threw in a 6 inch stack.
I had previously purchased some fiberglass rods from a big box store that were too stiff to make the right angle bend to reach the chimney pipe from inside my little wood stove These work much better for cleaning a chimney from below.
I purchased these rods so I could clean my flue from the bottom to the top. They worked extremely well, I was able to go through a 90 degree bend with ease. I would recommend this product to any one. I'm very happy and I'm saving $400 per year from hiring a chimney sweep.
